The hydroxy-aluminum pillared bentonite(OH-Al-bent) and aluminum pillared bentonite(Al-bent) were synthesized and characterized by XRD and SEM analysis. The yield of products and the adsorbent capabilities for Cr(Ⅵ) from aqueous solution were investigated, and the optimal experimental conditions including adsorption time, reagent dosage, the initial concentration of Cr(Ⅵ) and PH that might influent the adsorption performance were also investigated. It was observed that the adsorption capabilities of OH-Al-bent was better than Al-bent. The efficiency of Cr(Ⅵ) removal were better when the dosage of the sorbent was higher. And a reagent dosage of 7g/L, adsorption time of 60min, PH of 4 were selected as an optimum conditions.
